"Now this is Alistair," Jackie says. The older man in the bunk puts on a welcoming grin. "You started feeling poorly about day 8, did you not, Alistair?"

The grin turns sheepish. "Well, to tell the truth, I actually felt a little poorly on day 5, and a little more poorly day by day since then."

"What are your symptoms?"

"First I was feeling poorly, and then there was the fever and chills, right? Comes and goes. And muscle ache. And now I've got this cough, see?"

"Had it for about two days, right, Alistair?"

"Yes, ma'am. It's what they call a productive cough. I brings up this yellow-green ooze and sometimes a wee bit of blood."
